I have spent a lot of money here, yet I have found no chocographs, and the Moogle Meme has told me there are no more chocographs in the forest. Can anyone explain what I might've missed?

Quote me if I am wrong but do the chocographs and peices not become available after hitting certain beak levels? On this logic, keep on spending.

it may also depend on how far through the game you are

And that.

If Mene has told you that Choco can't find anymore chocographs in both the lagoon and the forest then you've gone as far as you've possibly can in that point in time. You have to continue on with the main story then return later.

However if Mene is telling you that Choco cannot find anymore chocographs in just the forest then I'm afraid you just have to keep digging in the lagoon.

And for anyone who actually did not give a toss what Mene said, just keep plugging on onto disc 4 sunshine!

What Erebus said fills it.

Definitely keep digging in Chocobo Lagoon. They're there, trust me. And money shouldn't be much of a problem; it's really pretty cheap to dig there.

hav u found it? i agree that the chocographs should be there (not depend on how far the main story goes nor ur beak level-yet to mention that ur beak level's going up much from chocograph's high points, right?) , u just need to dig more. and actually it's quite fun to dig in the lagoon, don't u agree? come on, it just 1 step away! hehe..
